ABSTRACT

Embodiments described herein are related to a sports training device. The sports training device may include a base structure having a supporting element and a shaft coupled to the base structure such that the shaft is selectively raised or lowered relative to the base structure. A resilient rod may be coupled to the second end of the shaft and disposed. The resilient rod may be capable of bending to absorb an impulse and returning to a first resting position along. A longitudinal rod structure may be coupled to the resilient rod. The longitudinal rod structure may be disposed along the first axis and capable of rotating with the bending of the resilient rod. A reference object may be coupled to an end of the longitudinal rod structure. The reference object may be disposed along or proximate to a target trajectory of a sports ball.

BACKGROUND

In some sports, a goal may refer to either an instance of scoring, or to the physical structure or area where attacking team may send a ball or other sports implement to score points. The structure of a goal varies from sport to sport, and one is placed at or near each end of a playing field or court for each team to defend. In some sports, each goal structure can consist of two vertical posts, sometimes called goal posts, supporting a horizontal crossbar. A goal line marked on the playing surface between the goal posts can demarcate a goal area. In some sports, the objective is to send the ball or other sports implement between the goal posts, under or over the crossbar (depending on the sport), and across the goal line. Other sports may have other types of structures or areas where the ball or other sports implement must pass through.

In basketball, for example, the primary object is to score by shooting (i.e., throwing or sending) a sports ball (e.g., basketball) into a goal, often referred to as a basket or a hoop. A basket is scored when the ball passes completely through the basket ring from above. In some conventional basketball playing environments, a basket can consist of a metal ring and a net that is attached to the ring and is disposed downward from the ring. The basketball goal may include a backboard that is disposed substantially vertically behind the ring from facing a direction of a basketball playing environment. When shooting a basketball, the basketball may travel through the ring from above at various angles according to different trajectories. Some trajectories have been shown to result in improved basketball shooting efficiency. For example, a basketball that passes through the ring at or near 45 Degrees may result in less contact with the ring and resulting in a smaller margin for scoring a basketball.

DETAILED DESCRIPTION

Embodiments described herein are related to a sports training device and system. As mentioned above, many sports involve participants shooting (e.g., launching, throwing, tossing, etc.) sports equipment (e.g., a sports ball such as a basketball) into a goal (e.g., a basketball hoop). Various strategies and training techniques are used to determine the most efficient and accurate method for scoring goals. For example, in basketball various arm angles and configurations, basketball launch points, shooting launch speed, etc. can be modified to alter a trajectory of basketball being shot at a basketball hoop. Various trajectories have been shown to improve a sports participant chance of successfully scoring a goal (e.g., making a basket). For example, in some instances, such as in a conventional basketball environment, basketballs launched with a trajectory that arrive at the hoop at or near 45 Degrees from the ground are more likely to pass through the hoop.

Conventionally, basketball shooting devices are large, expensive, and lack portability. Some conventional basketball shooting devices focus on basketball retrieval and delivery to improve shooting repetition efficiency. Other conventional basketball shooting devices are designed to target a shooting form and are sometimes applied or worn by an athlete. Other conventional basketball shooting devices are designed to simulate a live basketball game environment such as by simulating defending players and game conditions. These conventional basketball shooting devices do not teach or provide feedback associated with a trajectory of a basketball when being shot (e.g., launched) at a basketball goal.

More generally, conventional sports training equipment does not provide devices or mechanisms that include a reference point disposed along or adjacent to a sports ball's (or more generally sports projectiles (e.g., a hockey puck, a frisbee, a shuttlecock, etc.)) trajectory (e.g., such as when being shot at a goal). Additionally, conventional sports devices that track or analyze sports equipment trajectories often involve expensive trajectory tracking equipment such as cameras, sensors, and the like that tracks the sports equipment and provide a post mortem analysis of trajectories. These conventional systems and devices are unable to provide live feedback and often involve extensive setup, calibration, and power requirements to run or operate. Additionally, conventional devices and system are not portable, lightweight, or easy to setup and operate.

The devices and systems disclosed herein provide a sports training device and/or system. The sports training device and/or system may include a durable device capable of easy transport, setup, and disassembly for sports ball trajectory training. For example, the sports training device may be used for basketball shooting practice. The sports training device may provide a height adjustment and placement to visually aid a person shooting a sports ball to identify a target arc and trajectory to shoot the ball into the goal (e.g. basket). For example, the target arc and/or trajectory may be associated with the ball entering the goal at a desired angle (e.g., at or near 45 Degrees from the ground).

In some embodiments, the sports training device may include a base structure having a supporting element and a shaft coupled to the base structure such that the shaft is selectively raised or lowered relative to the base structure. A resilient rod may be coupled to the second end of the shaft and disposed. The resilient rod may be capable of bending to absorb an impulse and returning to a first resting position. A longitudinal rod structure may be coupled to the resilient rod. The longitudinal rod structure may be disposed along the first axis and capable of rotating with the bending of the resilient rod. A reference object may be coupled to an end of the longitudinal rod structure. The reference object may be disposed along or proximate to a target trajectory of a sports ball.

In some embodiments, a sports training feedback system includes a sports trajectory reference device. The sports trajectory reference device may include a stability structure that includes one or more collapsible legs to balance the sports trajectory reference device. The sports trajectory reference device may include a height adjustable structure coupled to the stability structure. The height adjustable structure may include one or more rods designed to translate relative to the stability structure to heighten or shorten the sports trajectory reference device. The sports trajectory reference device includes a flexible rod structure coupled to the height adjustable structure. The flexible rod structure may receive an impact from a sports ball and bend relative to the height adjustable structure to absorb the impact form the sports ball. The sports trajectory reference device may be disposed between a sports goal and the sports ball. The sports ball may be targeted at the sports goal and an end of the flexible rod structure may be disposed along or proximate to a target trajectory of the sports ball. The sports training system may further include a feedback device that communicates with the sports trajectory reference device. The feedback device may provide one or more of an auditory feedback or a visual feedback indicative of the sports ball contacting the sports trajectory reference device. For example, an auditory feedback or a visual feedback is provided when an object contacts the stability structure, the height adjustable structure, and/or the flexible rod structure.

In some embodiments, a basketball arc shooting instructor system includes an apex reference device. The apex reference device may include a stability structure that includes one or more collapsible legs to balance the apex reference device. The apex reference device may include a height adjustable structure coupled to the stability structure. The height adjustable structure may include one or more rods designed to translate relative to the stability structure to heighten or shorten the apex reference device. The apex reference device may include a flexible rod structure coupled to the height adjustable structure. The flexible rod structure may be disposed in a vertical position and be configured to receive an impact from a basketball and bend relative to the height adjustable structure to absorb the impact from the basketball and return to the vertical position. The apex reference device may be disposed between a basketball hoop and the basketball. The basketball may be targeted at the basketball hoop and the flexible rod structure may be disposed at or below an apex of a target trajectory of the basketball.

The devices and systems disclosed herein have advantages over conventional solutions. The device may be assembled easily. The device may have a flexible top structure, and in some embodiments include springs, that allow for bending or movement if a sports ball strikes the structure. The flexible pole (and/or springs) may prevent the device from tipping over. In some embodiments, atop the flexible pole is a small visible reference point that give a sports participant a point of reference to aim and achieve a target trajectory (e.g., to achieve a desired basket entry angle) of the sports ball. For example, if the sports ball arc is too high, the visible reference point shows the sports participant the different between the ball and the reference point. If the balls arc is too low, the feedback is given by the movement of the pole. A sports participant can use this on demand feedback to adjust and improve their shooting technique. In some embodiments, the sports training device may include rods and height adjustable structures to provide a minimally obstructive view to the sports participant. For example, the sports participant can use the device to align their shooting of the ball by using the device as a mechanism for centering the ball with the sports goal.

FIG. 1 illustrates a perspective view of a sports training feedback system 100, according to certain embodiments. The sports training feedback system 100 may include a sports goal 102, a sports trajectory reference device 108, and a sports ball 110. The sports trajectory reference device 108 may be disposed between a sports participant 106 and a sports goal 102. The sports trajectory reference device 108 may include a reference point 112 (e.g., a separate reference object or an end of a rod or pole).

As shown in FIG. 1, the sports goal 102 may include a basketball hoop 116 having a ring and a net disposed a distance from the ground (e.g., 10 feet in a conventional basketball playing environment). The ring may be supported by a backboard 114. Although many embodiments illustrate and describe aspects of the sports trajectory reference device 108 in a basketball playing environment, the sports trajectory reference device 108 may be employed in many different sporting environments. For example, the sports goal 102 may include a soccer goal or a hockey goal and the sports ball 110 may be a soccer ball or a hockey puck.

In some embodiments, the sports ball 110 is targeted and/or launched along a trajectory 104 towards the sports goal 102. The trajectory 104 may include an arc having an apex. The reference point 112 may be used to identity a target location of the apex of the arc. For example, the sport trajectory reference device 108 may be aligned in the field of view of the sports participant 106 such that a central axis of the sports trajectory reference device 108 aligns with a target location where the sports ball 110 is to arrive at the sports goal 102 (e.g., center of the basketball hoop 116). Alternatively, in other sports a target may be disposed in an off-center location of the sports goal 102, such as, for example, a corner of a soccer goal.

In some embodiments, as mentioned previously, a desired outcome of shooting the sports ball 110 may include shooting the sports ball 110 such that the sports ball 110 arrives and passes through the basketball hoop 116 at or near a 45 Degree angle (e.g., 40 to 50 Degrees). The sports trajectory reference device 108 may be disposed at a location between the sports participant and the sports goal such that the reference point 112 (e.g., an end of the sports trajectory reference device 108) is disposed at or near a target apex of the trajectory 104. For example, the trajectory of a basketball shot toward the basketball hoop may have a parabolic trajectory with an apex at a location near a midpoint between the sports participant 106 and the sports goal 102.

In some embodiments, the sports trajectory reference device 108 is self-balanced and easily moveable from various locations within the sporting environment. For example, as will be discussed in later embodiments, the sports trajectory reference device 108 may include one or more legs designed to contact a ground surface. For example, as shown in FIG. 1, the base may include three or more collapsible legs configured to contact a surface. The device may be free from attachments and/or connections to the sports playing environment and can be moved within the sports playing environment without the need of specialized lifting tools.

In some embodiments, the sports training feedback system 100 may include a feedback device. In some embodiments, the feedback device may be a device separate from the sports trajectory reference device 108, and in other embodiments, the feedback device may be integrated with or otherwise coupled with the sports trajectory reference device 108. The feedback device may include a device capable of providing auditory feedback (e.g., speakers, a horn, percussive tools, etc.) and/or a device capable of providing visual feedback (e.g., a light emitting diode (LED), a flashing light, a coordinated colored light system, etc.). The feedback device is coupled to the sports trajectory reference device 108 such that feedback is provided to the sports participant 106 when the sports trajectory reference device 108 is contacted (e.g., contact between the sports ball 110 and the sports trajectory reference device.

In some embodiments, multiple sports trajectory reference devices 108 may be disposed along or proximate to (e.g., below) various points (e.g., apex, inflections points, etc.) of the trajectory 104 of the sports ball 110. The multiple disposed locations of the sports trajectory reference devices 108 may be used to track critical points along the trajectory 104 that can be used as reference points to train a sports participant 106 to shoot along a desired target trajectory.

FIG. 2 illustrates a perspective view of a sports training device 200, according to certain embodiments. The sports training device 200 includes a base structure 202, a shaft 204, a flexible rod structure 206, a longitudinal rod structure 208, and a reference object 210.

The base structure 202 may include one or more supporting elements designed to maintain balance and provide stability to the sports training device 200. In some embodiments, the one or more supporting elements include one or more legs 212 designed to contact a ground surface to provide stability. For example, as seen in FIG. 2, the base structure may include a tripod having three equally spaced legs 212. The legs 212 may be aligned to arrive at a common point disposed proximate an end of the shaft 204.

In some embodiments, the legs 212 of the base structure 202 may include contact elements such as a substantially flat surface designed to contact a ground surface. The contact elements may include friction increasing surfaces (e.g., having a relatively higher coefficient of friction than the legs 212) that reduce sliding of the sports training device 200 across a ground surface and/or provide greater stability. The 212 legs may include weighted portions proximate the ground surface to increase the stability of the sports training device 200.

In some embodiments, the base structure 202 may include a central bar 214. The central bar 214 may form a hollow channel disposed along a central axis of the central bar 214. For example, the hollow channel may be formed to receive the shaft 204. The shaft may be selectively translatable within (e.g, telescope within) the central bar 214 to raise or lower the shaft relative to the base structure. The raising and/or lowering of the shaft 204 relative to the base structure 202 may increase and/or decrease an overall height of the sports training device 200.

As shown in FIG. 2, the base structure may include supporting rods 216 each coupled to a leg 212 and the central bar 214. The central bar 214 may translate up and/or down relative to the legs 212 while the supporting rods 216 maintain a fixed length and/or distance between the central bar and the supporting rods 216. In some embodiments, the one or more legs 212 are collapsible. For example, the central bar 214 may translate downward relative to the legs 212, and the supporting rods 216 pull the legs 212 toward the central bar into a collapsed position as will be discussed further in association with FIG. 5. The central bar 214 may translate upward relative to the legs 212 to push the legs 212 outward to create a base of stability for the sports training device 200.

Alternatively or additionally, the base structure 202 may include a coupling device such as a grasping and/or clamping device that is capable of coupling to an external structure. For example, the coupling device may couple to sports equipment such as a ball rack to stabilize the sports training device 200. In another example, the coupling device may couple to another structure adjacent to the sports playing environment such as a wall or stanchion.

As seen in FIG. 2, the shaft 204 is disposed between the base structure 202 and the flexible rod structure 206. The shaft 204 may be coupled to the base structure 202 and/or the resilient rod structure. For example, the shaft 204 may be selectively removable from the base structure and/or selectively disconnected from the flexible rod structure 206. The shaft 204 may include one or more rods disposed in a substantially vertical position. The shaft 204 may translate vertically relative to the base structure 202 to heighten or shorten the sports training device 200. The claims 218A-B may be selectively engaged and loosened to secure or released a hold on an associated rod 220A-B. FIG. 2 illustrates an embodiment with two rods 220A-B and two clamps 218A-B, however, more or less clamps and rod may be used to achieve similar outcomes for taller and/or shorter applications.

As seen in FIG. 2, the shaft 204 may include one or more rods 220A-B held together by clamps 218A-B. A first rod 218B may be disposed within a first rod 220A and be capable of translating within the first rod 220A. For example, a portion of the first rod 220A may telescope within the second rod 220B. In some embodiments, as mentioned previously, a portion of the shaft 204 (e.g., a portion of the first rod 220A) may be disposed within the central bar 214 of the base structure 202. For example, the first rod 220A may telescope within a portion of the base structure 220.

In some embodiments, the one or more rods 220A-B may include one or more height indicators depicted on a surface of each of the rods. For example, each rod may display a current length contribution of that rod to the overall height of the sports training device 200. In another embodiment, the height indicator may indicate common reference heights such as an indication when a second rod 220B will be removed from a first rod 220A if extended any further.

In some embodiments, the one or more rods 220A-B are selectively removable from each other. For example, for improved portability each rod may be separable and stored individually. However, in other embodiments a blocking element may be disposed to prevent a first rod 220A from be removed from the inside of the second rod 220B.

As shown in FIG. 2 the sports training device 200 includes a flexible rod structure 206 disposed between the longitudinal rod structure 208 and the shaft 204. In some embodiments, the flexible rod structure 206 is coupled to the shaft 204 and/or the longitudinal rod structure 208 using one or more fasteners. For example, the flexible rod structure 206 may include a male or female threaded fastener component capable of coupling the flexible rod structure 206 to an associated threaded fastener component on the longitudinal rod structure 208 and/or the shaft 204.

The flexible rod structure 206 is comprised of a resilient material capable of bending and/or flexing when receiving an impact directly or received through the longitudinal rod structure 208. For example, the flexible rod structure 206 may be disposed in a resting position (e.g., the device as show at resting position 224) along a first axis (e.g., a vertical position along a vertical axis). The sports training device 200 may receive an impulse (e.g., from a collision between a sports ball and the sports training device 200) and the flexible rod structure 206 may flex into another position (e.g., the device as shown in flexed positions 226A-B) and return to the resting position 224 after the duration of the impulse. This flexing and/or bending of the flexible rod structure 206 alters the disposition of the longitudinal rod structure 208 coupled to an end of the flexible rod structure. The movement of the longitudinal rod structure 208 allows for the sports training device 200 to absorb contact from objects (e.g., sports equipment such as a basketball) without the device tipping over or being dislodged.

In some embodiments, as seen in FIG. 2, the flexible rod structure 206 may include an elastic component such as a spring 222. The spring 222 may be in a compressed configuration while in the resting position 224. The spring 222 may be extended when in the flexed position 226A-B and apply a compression force to bring the sports training device 200 back into the resting position 224.

As shown in FIG. 2, the sports training device 200 includes a longitudinal rod structure 208. The longitudinal rod structure may be disposed along a first axis (e.g., a vertical axis) when in the resting position 224 and disposed along a second axis when in a flexed position 226A-B.

In some embodiments, as will be discussed further in later embodiments, the longitudinal rod structure 208 may include one or more modular members that selectively couple one with another. The modular member may include tube shaped rods and connectors that connect the tube shaped rods together. In some embodiments the connectors may be integrated to an end of each of the tube shaped rods. The modular member may be selectively disconnected from each other, for example, for increased portability.

In some embodiments the longitudinal rod structure 208 is rigid and rotates in accordance with the flexing of the flexible rod structure 206. In other embodiments, the longitudinal rod structure 208 is comprised of flexible matter that flexes when receiving an impulse (e.g., such as from a contact from a sports ball).

As shown in FIG. 2, the sports training device 200 includes a reference object 210 disposed at an end of the longitudinal rod structure 208. The reference object 210 may be integrated with or selectively removable from the longitudinal rod structure 208. The reference object 210 may be disposed at a position along and/or proximate a trajectory of a sports ball. For example, the reference object 210 may be disposed at a position below an apex of a trajectory of a basketball being shot at a basketball hoop. The reference object 210 may be an easily visible object such as a bright colored object and/or an object having a commonly contrasted color.

In some embodiments, the reference object may be made of a lightweight material (e.g., foam, plastic, etc.) In some embodiments, the reference object is circular. For example, the reference object 210 may include a ball (e.g., a foam or plastic ball). In some embodiments, the reference object includes a flat visible surface such as a disk. In some embodiments, the sports training device 200 includes a light source integrated with or external to the reference object that illuminates the reference object 210 (e.g., to improve visibility of the reference object).

FIG. 3 illustrates an exploded view of a sports training device 200, according to certain embodiments. Some elements in FIG. 3 may have the same number as other figures, and these elements may be substantially similar to those elements having the same number in other figures. As previously described the sports training device 200 may include a base structure 202 coupled to a shaft 204. The shaft is coupled to a flexible rod structure 206 which is coupled to the longitudinal rod structure 208. The sports training device may further include a reference object 210 disposed at an end of the longitudinal rod structure 208.

In some embodiments, the shaft 204 can be adjustable to different heights by using the clamps 218A-B. The clamps 218A-B may include height adjusting knobs that engage and disengage with the rods 220A-C to allow movement and secure the rod again at a desired height of the sports training device 200. For example, the desired height can be made by adjusting the rods using measurement indicators 302 disposed on a surface of one or more of rods 220A-C.

As shown in FIG. 3, the shaft 204 includes a connector 304 that can attach the shaft to the flexible rod structure 206. The flexible rod structure 206 may allow for the top portion (e.g., the flexible rod structure 206 and the longitudinal rod structure 208) of the sports training device to flex if struck by an object (e.g., sports equipment such as a sports ball). The flexing of the flexible rod structure 206 may, in some cases, prevent damage to the sports training device, and in some cases, prevent the sports training device 200 from tipping over.

In some embodiments, the flexible rod structure 206 includes threaded bores to receive threaded fasteners (e.g., such as threaded fasteners included on the shaft 204 and/or longitudinal rod structure 208). In some embodiments, the flexible rod structure couples to one or more of the shaft 204 and/or the longitudinal rod structure 208 using other connecting techniques (e.g., fasteners, brazing, riveting, clinching, pinning, stapling, adhesive bonding, soldering, and the like). In some embodiments, one or more of the base structure 202, shaft 204, flexible rod structure 206, and/or longitudinal rod structure 208 are integral one with another.

In assembly, the base structure 202 is placed on a ground surface, with the legs 212 extended out, and positioned at the calculated distance between the sports participant (e.g. sports participant 106 of FIG. 1) and the sports goal (e.g., sports goal 102 of FIG. 1). In some embodiments, the shaft 204 is stored with the base structure 202, and in other embodiments the shaft 204 may be decoupled from the base structure 202 during transportation of the sports training device 200. After the base structure 202 and the shaft 204 are assembled, the flexible rod structure 206 is coupled with the shaft 204. The longitudinal rod structure 208 coupled with the reference object may then be coupled to the flexible rod structure. Once assembled, the rods 220A-C of the shaft may be translated to heighten or lower the overall height of the sports training device 200.

FIG. 4 illustrates a perspective view of a fully assembled sports training device, according to certain embodiments. Some elements in FIG. 3 may have the same number as other figures, and these elements may be substantially similar to those elements having the same number in other figures. As discussed previously and shown in FIG. 4, the sports training device 200 may include a base structure 202, a shaft 204, a flexible rod structure 206, a longitudinal rod structure 208, and a reference object 210.

As shown in FIG. 4, the shaft 204 may be fully extended and supported by rods 20A-C held together using clamps 218A-B. A third rod 220C may telescope within a second rod 220B, and a first rod 220A. The second rod 220B may telescope within the first rod 220A.

In some embodiments, the clamps include height adjustment knobs that allow for quick engagement and disengagement of the clamps 218A-B on the rods 220A-C allowing translation of the rods 220A-C relative to the other components of the sports training device 200.

As shown in FIG. 4, the rods 220A-C may include measurement indicators that indicate an estimated height of the sports training device 200 with the current configuration between the rods 220A. In some embodiments, the measurement indicator 302 may include reference indicators for common shooting locations. For example, one or more of the marks may indicate a height to set the sports training device 200 for an individual to shoot from a location on the sports playing environment (e.g., free throw line, three point line, etc.). In another example, the measurement indicators may be associated with the relative height of the sports participant.

FIG. 5 illustrates a view of a dissembled sports training device 200, according to certain embodiments. Some elements in FIG. 3 may have the same number as other figures, and these elements may be substantially similar to those elements having the same number in other figures. As discussed previously, the sports training device 200 may include a base structure 202, a shaft 204, a flexible rod structure 206, a longitudinal rod structure 208, and a reference object 210.

As shown in FIG. 5, the base structure includes legs 212, supporting rods 216, and a central bar 214. In a collapsed position, as seen in FIG. 5, the legs 212 are disposed proximate the central bar 214 in a near parallel position to the central bar 214. The supporting rods 216 are tucked in between the legs 212 and the central bar 214. In the collapsed position, the central bar 214 supporting rods 216, and the legs 212 are disposed substantially along a single axis (e.g., in a primary dimension). The base structure 202, in the collapse position, may be designed to take up as little area in the perpendicular dimensions from the primary dimensions.

As shown in FIG. 5, in the collapsed position, the shaft 204 may be mostly, if not entirely, disposed within the base structure 202. For example, as discussed previously, the shaft 204 may include one or more telescoping rods. A first rod may telescope within a second rod and one or more of the rods may telescope within the base structure. In the collapsed position, a major portion of each rod may be telescoped (e.g., to reduce the length of the shaft 204 to improve portability). In some embodiments the shaft 204, may be transported with the base structure, and in others, the shaft 204 may be selectively removed from the base structure.

As shown in the FIG. 5, the sports training device 200 includes a flexible rod structure 206. The flexible rod structure may include a rod portion and a spring portion. The rod portion and the spring portion may be made from the same material (e.g., a resilient metal) and/or integral one with the other. Alternatively or additionally, the rod portion and the spring portion may be coupled using machining techniques (e.g., fasteners, brazing, riveting, clinching, pinning, stapling, adhesive bonding, soldering, and the like). The spring portion may include a spring 222. The spring 222 may be disposed on the outside of a centrally disposed rod. The centrally disposed rod may include an elastic material capable of flexing or bending in line with the spring. 222. The flexible rod structure may include one or more connecting elements to couple with the shaft and the longitudinal rod structure 208.

As shown in FIG. 5, the sports training device 200 includes a longitudinal rod structure 208. The longitudinal rod structure 208 may include a series of modular members 502. The modular members 502 may include tube shaped rods. The modular members 502 may be coupled to each other via connectors 504. Each connector 504 may be integrated with or otherwise connected to (e.g., using machining techniques such as fasteners, brazing, riveting, clinching, pinning, stapling, adhesive bonding, soldering, and the like) each modular member 502.

In some embodiments, the each modular members 502 may form a hollow recess along a central axis of each of the modular members 502. The longitudinal rod structure 208 may include an elastic rope 506 connected to a first end of the longitudinal rod structure 208 and a second end of the longitudinal rod structure 208. The elastic rope 506 may be disposed within each recess of the one or more modular members 502. When dissembled, the elastic rope 506 allows for the individual modular members 502 to remain connected in a portable manner (e.g., for ease of transportation and/or improved portability of the sports training device 200).

In some embodiments, in a disassembled or collapsed position, the flexible rod structure 208 may be coupled together only by the elastic rope 506. In some embodiments, the elastic rope 506 provides a compressing force to bring the longitudinal rod structure back into an upright position after receiving an impulse from an external object (e.g., a sports ball such as a basketball).

In some embodiments the longitudinal rod structure 208 includes multiple elastic ropes 506. Each elastic rope may couple two modular members 502 together. Each elastic rope 506 may be coupled to an ends of two different modular members 502. For example, the modular members 502 may remain coupled in a dissembled configuration such as when stowed (e.g., to improve portability of the sports training device 200).

As shown in FIG. 5, the sports training device 200 may include a reference object 210 disposed at an end of the longitudinal rod structure 208. The reference object may be selectively removable from the longitudinal rod structure (e.g., for ease of transportation and/or improved portability of the sports training device 200).

In some embodiments, the entirety of the sports training device 200 may be designed to fit in a single bag or other transportation device. For example, the sports training device 200 may be brought to various sports playing environments and assembled and dissembled and brought to another sports playing environment without the need of specialized transportation tools or an extensive setup and/or disassembly.

FIG. 6 illustrates a side view of a basketball arc shooting instructor system 600, according to certain embodiments. Some elements in FIG. 3 may have the same number as other figures, and these elements may be substantially similar to those elements having the same number in other figures. As shown in FIG. 6, the arc shooting instructor system includes an apex reference device 608A-C disposed between a shooting location 602A-C and a basketball hoop. The apex reference device 108A-C may be selectively moved between the shooting location 602A-C and the basketball hoop 602 to be disposed at a position at or below the trajectory 604A-C of the sports ball.

As shown in FIG. 6, a sports participant at shooting location 602A may shoot a basketball with trajectory 604A. The trajectory may include an arc with an apex where the basketball will be at its highest point across the trajectory. The apex reference device 608A is disposed at a position just underneath the apex of the trajectory. The apex reference device 608A provides a visual indication to the sports participant at shooting location 602A where to aim and target the apex of the trajectory when shooting the basketball. For example, as mentioned previously, a desired outcome of shooting the ball is to shoot the ball such that the ball passes through the basketball hoop. In a further example, the target trajectories 604A-C may be planned such that the basketball passes through the basketball hoop 602 at or near 45 Degrees relative to the ground (e.g., 40 to 50 Degrees).

As shown in FIG. 6, as the sports participant moves closer to the basketball hoop 602 the target trajectory is changed. For example, at shooting location 602B, the target trajectory 604B may include an apex that is closer to the basketball hoop 602 and/or shorter in distance from the ground. The apex reference device 608B may be placed closer to the basketball hoop 602 to align with the apex of the new trajectory 604B. The apex reference device 608B may also be shortened (e.g., by adjusting the height of the device as described herein). FIG. 6 further illustrates a third exemplary shooting location 602C and corresponding trajectory 608C. The apex reference device 608C may be disposed at a point at or below the apex of the target trajectory 604C

In some embodiments, the device may be heightened and/or shortened to account for a shooting height at each shooting locations 602A-C. For example, shorter and/or taller sports participants may launch the ball from different starting heights which may result in different locations of the apex of the target trajectories 604A-C.

FIG. 7 illustrates a perspective view of an uncoupled sports trajectory reference device 700, according to certain embodiments. The sports trajectory reference device 700 (sometimes referred to as an apex reference device in some embodiments) may include a stability structure 702 having one or more collapsible legs to balance the sports trajectory reference device. The stability structure 702 may include other details and features as described in association with base structure 202. The sports trajectory reference device 700 may include a height adjustable structure coupled to the stability structure. The height adjustable structure 704 may include one or more rods configured to translate relative to the stability structure 702 to heighten and/or shorten the sports trajectory reference device 700. The height adjustable structure 704 may include details and/or features associated with shaft 204.

The sports trajectory reference device 700 may include a flexible rod structure 706 capable of connecting to the height adjustable structure 704. The flexible rod structure 706 may receive an impulse from a sports ball and flex relative to the height adjustable structure 704 to absorb the impulse from the sports ball.

In some embodiments, the sports trajectory reference device is disposed between a sports goal and the sports ball. The sports ball may be targeted at the sports goal and an end of the flexible rod structure 706 may be located at a point along or proximate to a target trajectory of the sports ball.

FIG. 8 illustrates reference locations of an apex reference device on a basketball playing environment 800, according to certain embodiments. As shown in FIG. 8, the basketball playing environment 800 may include a basketball hoop 802 and various lines demarking common reference locations 802-812 within the basketball playing environment 800. In some conventional basketball playing environments, the basketball hoop is disposed at a height of 10 feet from the playing surface of the basketball playing environment 800. A first reference location 806 is located at the free throw line. Conventionally, the midpoint of the free throw line is disposed 15 feet from a point on the playing surface directly underneath the basketball hoop 802. A second reference location 804 is midway between the basketball hoop 802 and the free throw line. A third reference location 808 is commonly identified as the high school three point arc and in some conventional basketball playing environments is disposed 19.75 feet from the point on the playing surface directly underneath the basketball hoop 802. A fourth reference location is commonly identified as the collegiate three point line and in some conventional basketball playing environment is disposed 20.75 feet from the point on the playing surface directly underneath the basketball hoop 802. A fifth reference location 812 is commonly identified as the professional three point line and in some conventional basketball playing environments is disposed at 23.75 feet along an arced portion and 22 feet along the straight line portion proximate the corners of the basketball playing environment 800 from the point on the playing surface directly underneath the basketball hoop 802.

In some embodiments, the reference locations 804-812 can be used to determine a relative location of an apex reference device (e.g., apex reference device 608A-C of FIG. 6). The reference locations on the basketball can be used to determine approximate horizontal distances from the basketball hoop 802. This horizontal distance can be combined with the shooting height of a sports participant to determine a location for an apex reference device to be disposed. In some embodiments, target shooting trajectories from common shooting locations may be mapped out and calculated apex reference device location can be marked (e.g., to provide easy reference to multiple location the apex reference device is to be placed). For example, a visual indicator (tape, markings, etc.) may be placed on the playing surface of the basketball playing environment 800 to mark multiple locations the apex reference device is to be placed corresponding to multiple shooting locations. A sports participant may participate in a basketball shooting training exercise involving multiple shooting location and can move the apex reference device between marked locations as previously calculated and indicated by the visual indicators on the playing surface.
